An inquiry launched by the equality and human rights watchdog into the “chronic lack” of accessible housing has been welcomed by campaigners, but they warned that it must also look at whether such housing is affordable for disabled people.

The inquiry will examine the extent of what EHRC said was a “chronic” shortage, the experiences of disabled people over the last three years, and the consequences for those who have not found appropriate housing on their right to independent living.

It will also look at the impact of government policy, the availability of support services, and whether local authorities are complying with their duties under the Equality Act’s public sector equality duty and ECHR.

And the inquiry will examine the steps being taken by councils and social housing providers to increase the provision of accessible and adaptable housing, through planning and building regulations.

Part of the inquiry’s focus will be on how councils and social housing providers assess disabled people’s need for accessible housing and identify a suitable property, and on how the disabled facilities grants system – and equivalent grants in Scotland – are operating.

The inquiry, which is due to report early in 2018, will cover England, Scotland and Wales.

Zara Todd, community activities manager for the Norfolk-based disabled people’s organisation Equal Lives, said: “We would welcome any inquiry into the lack of accessible housing because it’s a big issue for disabled people across the country.

“If you don’t have somewhere that you can live, there are lots and lots of additional barriers to getting the other things you need in order to achieve independent living.

“It’s a crucial part of disabled people realising their rights and having independence.”

Neither was completely accessible to her, so she had to settle for a property that was partly inaccessible.

She also told the committee that when she bought an accessible flat in London, she was told by the developer that she was the first disabled person to have been able to afford to buy one of the many accessible properties it had built.

She told Disability News Service this week: “There are particular issues around the availability of affordable housing, so [it’s important for the inquiry to consider] not just accessible housing but housing that disabled people can afford.”

She said it was also “very unclear” what responsibilities landlords had when renting properties to disabled tenants.

This meant that disabled people who could not afford the accessible housing that was available, and did not meet the criteria for council housing, were “being consigned to being in inaccessible properties or homeless”.

She added: “Accessibility is not just about physical accessibility. It is also about financial accessibility.

“I would hope that EHRC would take that into consideration when they are doing their investigation.”

Tracey Lazard, chief executive of Inclusion London, which was involved in EHRC’s discussions about its plans to hold the inquiry, also welcomed the announcement.

She said: “Housing is a priority issue for disabled people, and as research has evidenced, there is a chronic situation with a lack of genuinely affordable, accessible and adaptable properties available.

“The issue is also wide-ranging, including a lack of support to enable disabled people to maintain their tenancies, and discrimination and barriers faced by, for example, people with mental health support needs in the private rental market.

“Whilst we are pleased that the EHRC is now giving more attention to disability equality in housing, we hope that the recommendations from this inquiry are as robust and critical as they need to be [about]the impact on disabled people of current housing policy and that they will have the power to influence the real change that is needed at national, regional and local authority levels.”

She said: “We welcome the EHRC inquiry into the chronic lack of accessible housing and are pleased that it will focus not only on the lack per se but also on the impact that the lack of accessible housing and housing support has on independent living.”

Bott gave evidence alongside Todd at the women and equalities committee’s evidence session in October.

She told the committee about one disabled man who had to crawl up the stairs of his rented property to get to his bathroom and bedroom.

After years of waiting on his local housing trust’s list for an accessible property, he was told that he was no longer eligible to be on that list because of a rule change.

Bott told the committee that this trust was having to cope with the “squeeze” on accessible one-bedroom properties caused by disabled people having to downsize because of the government’s bedroom tax.

David Isaac, EHRC’s chair, said: “Living independently is one of the most important issues for disabled people across the UK, yet only a small percentage of local authorities have policies to deliver and monitor the number of accessible homes being built.

“We are using our unique legal powers to hold this inquiry into the chronic lack of accessible housing for disabled people as well as the many barriers faced by those who need to adapt homes to their specific needs.

“It is to society’s shame that rights of disabled people have stalled, and we need to ensure they are no longer left behind in all areas of life, including housing and independent living.”
